How can I read a 3D-point set from a csv-file with X,Y,Z coordinate (column 1-3) and the fourth column has a stress-value and then color points according to the stress?
Hi Benedikte,
Can you post a small example of your data? Thanks
The content of the csv-file is like this (first rows), with X-coordinate, Y-coordinate, Z-coordinate and dCSC is a change in stress. I would like the colour of the points to represent the magnitude of the stress:
X,Y,Z,dCSC

Hey Benedikte -
You can read the CSV file with a simple Grasshopper script and create the points from the XYZ coordinates.

How do you translate, e.g., -43777.05177 to a color?

I would like to do that e.g. with a colorbar - gradually changing from one color to the other, depending on the magnitude. Is that possible in Rhino?
You can remap to a domain or use the gradient with the limits set to your bounds.

Thank you very much, that seems to work!
Just one additional question - is it possible to also show the legend / colorbar for the stresses?
